Pecíolo em uma angiosperma


Em botânica, chama-se pecíolo (por vezes também denominado estipe) a um caule que fica entre a bainha e
o limbo ou lâmina das folhas das plantas vasculares. Eixo de sustentação do limbo, geralmente cilíndrico. Algumas vezes possui uma expansão laminar, sendo então denominado pecíolo alado, como nas laranjeiras.


Em muitas espécies de plantas, as folhas não possuem pecíolo e chamam-se folhas sésseis, já em outras o pecíolo se liga diretamente ao centro do limbo chamando de peltada.
